EPPA H. RYoN, or WALTHAM, MASSACHUSETTS, AssIGNoR To onoMProN & KNoWLEs LOOIVI WORKS, OF SETTS. g

To aZZ whom t may concern.' l y Be it known that I, EPPA H. RYON, a citizen of the United States, residing at Wal` tham, in the countyof Middlesex-and State of Massachusetts, have invented a new and useful Twisting-Machine, of which the following is a specification. y

This invention relates to a twisting machine especially designed for twisting heavy material such'as the material from which cocoa mats are woven. Y

This material is stiff and very bulky and has presented certain difficulties to successful twisting operations. Some of these diiiculties arise from the inertiav of the heavy spools on which the material is delivered to the machine. It is an important object of my invention to provide a machine in which the axis of the spool is disposed perpendicularly to the axis of the rotatable frame in which the spools are mounted, so that the spools will not-revolve relative to the frame Vfrom their own inertia after the frame has come to rest.

@ther features of my invention relate to improved devices for detachably securing a spool in the rotatable frame, and to improved means for guidingthe material to be twisted as it advances from the spool to the point where it is delivered to the winding roll.

My invention further relates to arrangements and combinations of parts, which will be hereinafter described, and more particularly pointed out in the appended claims.

preferred form of my invention is shown in the drawings, in which* Figure 1 is a' side elevation of my improved twisting machine;

Figs. 2, 3 and 4 are transverse sectional views of the rotatable frame, taken along the lines 2-2, 3 3, and 4-4 of Fig. 1;

Fig. 5 is a sectional detail of one of the bearings of the rotatable frame, and

Fig. 6 is a detailed view of one of the devices for detachably securing a. spool in the frame.

Referring to the drawings I have shown a rotatable frame 10 comprising heads 11 and 12, connected by a plurality of tie rods 13, which rods in turn support a plurality of circular disks 14. VThe frame 10 is supbelt 24, to drive a bya presser roll 26, and rotated in definite WORCESTER, MASSACHUSETTS, A'VCORPORATION .OF MASSACHU- Y"rwisTINe-ivrAcieiIiniz.

The studs 27 and 30 coperate to rotatably support a spool S in the central recess of said disk. The shaft uponwhich the lever 28 is pivoted is extended laterally as shown in VFig. 6 and is thumb-nut 31, and spring32, the spring tending to holdv the stud 30 in operative position. -By thisV means the spool S is supported withits axis disposed perpendicularly'to the axis of the frame 10 and there is, therefore, no tendencyfor the spool to overrunl the framewhen the latter comes to rest.

VOppositely disposed guide openings 33 and 34 are provided in the disks 14 through which the material is led from each spool S to the head 12. This head is provided with a plurality of openings 35, preferably corresponding in number to the number of spools mounted in the frame 10, and uni-v formly The bearing 16Vof the frame 10 is provided with a plurality of guide openings 36,
